I´m probably going myself january or february. Been before, but never made it to a club yet! Watergate is supposed to be good, managed to miss Richie Hawtin & Ricardo Villalobos by one week last time I was there. I did have a few names of clubs to try out, but I have a memory like a goldfish. If I think of anything else I´ll post it. You try googling techno & berlin??
